embedded ethernet

hello:

i´m in my last year of university and now i´m working in my thesis and i´m trying to develop an embedded system able to transmit some medical signal via ethernet using an 8051 core micro and a RTL8019 nic.
For a while i have some problems understanding nic´s performance, could somebody help me?
Which mode of work do you suggest? Almost everybody talk about DMA access but i don´t completely understand it on RTL. I read lines that Jeremy Bentham dedicate to RTL in "Lean TCP/IP..." but i didn´t understand what does he exactly did...? I do not understand why to connect the 5th line of address (latching?)

Please, i need help, i´m spanish speaking, then , sorry my english...

Halo,

maybe you wanna check this out:

**broken link removed**

uIP AVR is code for driver RTL8019AS and including the uIP TCP/IP stack, I used it before and it works quite fine.

I think porting the driver code for RTL8019AS from AVR to 8051 should not a very big problem, since basically it is only some I/O ports commands.
hope it helps,

regards,

You can use Adam Dunkel's uIP TCP/IP stack for 8051 family microcontrollers. You can download it at https://www.sics.se/~adam/uip/index.html.
You can also find a port of uIP TCP/IP stack for Keil compiler at **broken link removed**. It also has the RTL8019 driver.
 

Re: embedded ethernet

Anyone has the same information for using a 8-bit microcontroller (ATtiny2313) and a cirrus chip? (CS9800A)

You can search DaviCom's product.
